摘要:
针对我国250 km/h城际动车组列车车内噪声控制问题，提出由问题导向式的被动噪声控制提升为低噪声正向设计，让车内声学指标变得可控。从声学技术规范、部件声学设计、整车声学仿真及优化、样车试验、减振降噪关键技术等方面着手，开展车内低噪声设计技术研究等方面工作。介绍了低噪声设计研究思路和声学设计参考标准，详细阐述了低噪声设计方法和试验方法。研究成果可为我国250 km/h城际动车组振动噪声控制提供依据，同时为动车组列车减振降噪提供参考。
Abstracts:
Targeted at the acoustic problem of 250 km/h intercity EMU, an effective inner acoustic index control method is proposed, which changes the passive way of problem-based noise control to low-noise forward design at the initial design stage. This approach proceeds from aspects of acoustics technical specification, component acoustics index design, whole train noise prediction and in situ noise experiment, key technology of vibration and noise reduction, in order to study the interior low-noise design. In this paper, the research idea and reference standards for acoustic design, the interior lownoise design and testing methods are elaborated in detail, which provide a basis for the 250 km/h intercity EMU noise reduction and references for EMU vibration and noise reduction in China.
